Extended Data Fig. 3: Correlation between G- and G′-band frequencies and FWHMs.

a, b, The frequencies (a) and FWHMs (b) are shown for the data displayed in Fig. 1d. The G′ spectra were fitted using four Lorentzians, as per ref. ²⁶. The results shown here are for the most intense G′ feature (named ‘L02’ in ref. ²⁶). The inset in a shows the behaviour of the four peaks.
